قَالَ حَمَّادٌ : وَأَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ عَقِيلٍ قَالَ : رَأَيْتُ شَعْرَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عِنْدَ أَنَسِ بْنِ مَالِكٍ مَخْضُوبًا
Hammad said:
'Abdullah ibn Muhammad ibn 'Uqail also informed us: "I saw the hair of Allah’s Messenger (Allah bless him and give him peace) dyed in the presence of Anas ibn Malik."
